To all 'whom it may concern.'

Be it .known that I, ILLIAM C. ANDER- soN, United States, residing the strippers t o place in the circumferential spaces of the inipaling roll to give the supporting shaft an adjustment on its axis, the

The devices for they could slide laterally on the shaft, they these purposes, together with other parts of had no pivotal movement thereon, being the machine are not here shown as they forni no part of my invention.

The impaling roll is provided with teeth or pins 4 which as usual lie in circumferential spaced rows and are set close enough toof feathers or ribs similar to the mounting of sliding clutches oii shafts. It was necessary therefore, in order to adjust and hold ether to exclude the seeds from between the teeth or pins, whereby said seeds are driven out from the pulp, and the latter is impaled upon the teeth.

The boxes 5 of the impaling roll are extended to form other boxes 6 for a rod 7, which lies back of and slightly above the roll.

8 are the pulp-stripper blades. These, at their upper ends are each independently pivotally mounted upon the rod 7, so that each blade may individually turn on said rod as an axis. E ach blade is formed as shown in Fig. 1, having its lower portion 9 concaved on an arc of considerable length, so that it lies between adjacent pin-rows and hugs the bottom of the space between the rows. The extremity of the blade is brought down to a chisel-like end, which lies closely against the bottom of the space. The upper end of each blade is formed with a rear shoulder or heel 10.

The boxes 6 are further carried up as plates 11, to form end guides for the vertically adjustable bar 1,2, which is acted upon by adjusting screws 13 at each end. The bar 12 extends between the two end guides 11 and has secured to its lower edge a cushion bar 14 preferably made of rubber. This cushion bar presses down upon the heels or shoulders 10 of all the stripper blades as seen in Fig. 2. Then all the strippers are new I the adjusting bar 12 is initially set down by the screws 13 to such an extent as to cause the cushion bar 14v to press all the strippers to their proper positions. Each stripper can yield individually against said cushion. Those that wear first, are, however, still kept to. place by said cushion bar, and the entire series thus remains operative. lVhen necessary, the adjusting bar 12 may be set down further to compensate for more general wear.

With this construction, all the advantages, which I have heretofore indicated, are attained. Each stripper is held in perfect place and its wear compensated for independently of the others. Each has its own relief before inequalities and obstructions, and all the strippers as a series may be continued to be used without regard to relative wear.

Having thus described my invention what 1 claim as new and desire to secure by Letters Patent, is
